IntroductionTypically, analog and digital blocks are verified independently with different simulation technology that varies in accuracy. When analog and digital blocks are combined in one simulation, due to capacity limitations of traditional simulators, verifying them together usually requires some additional modeling techniques that only approximate circuit behavior. In some cases, this can introduce false design errors causing engineers to spend a significant amount of time searching for the root cause.

FineSim is the first single executable product that allows designers to functionally verify mixed-signal SoCs seamlessly without the overhead of traditional solutions. In addition to enabling the designer to work with detailed parasitic information, the designer has complete control of accuracy vs. performance tradeoffs.

Combination of accuracy and performance in a single executable allows large, mixed-signal designs to be simulated with very accurate SPICE and FastSPICE solving techniques. This provides complete control of speed vs. accuracy tradeoffs throughout the entire design verification process

Provides unmatched performance through advanced SPICE and FastSPICE solvers, improving runtimes by 3X to 10X for single core simulations. With multi-core simulations, the performance scales linearly per core and can increase 20X to 30X or more, in some cases

Simulation Accuracy and PerformanceWith an improved architecture and better numerical solvers, FineSim delivers a 3X to 10X performance increase on a single core over existing commercial SPICE and FastSPICE simulators. FineSim allows the designer to take advantage of multiple circuitsolving techniques, such as hierarchical simulation recognition for memory structures, or multi-rate techniques for sensitive analog circuits and advanced RC reduction algorithms.

When multiple cores are used, the simulation performance can exceed 30X performance compared to other commercially-available products that use a single core, and also enables the handling of very large designs.

Superior Simulation CapacityFineSim enables SPICE-accurate analysis of very large, complex digital and analog/mixed-signal designs using multiple cores, achieving silicon accuracy never before possible in SPICE. Using multiple cores, FineSim has accurately simulated designs with multi-million transistors in full SPICE and matched measurements taken from silicon.

Static and Dynamic Electromigration and Voltage Drop AnalysisFineSim has an optional package for static and dynamic power analysis, as well as electromigration (EM) analysis. Designers can accurately calculate peak, average, and root-mean-square current values and graphically display and grade the results by severity levels for a quick visual analysis.
